CASA aside, I think we have two types of students, more so today then even a few years ago.
The first type is the original, pay as you go, lesson here, lesson there, bit in an RAA machine and so on till they either quit or achieve their goal. Somewhere amongst this they self study then sit the required exams.
The "new" type fronts up with cash or a government funded debt and expects continual training, in house exam schooling and a quick path towards their goal. These students should need less hours (perhaps).
Do we need new types of fight school, new parts for each, new ops manuals and new air operators certificates? I don't think so. I just quit as a CFI because at this stage in life the pay wasn't enough for me to be inclined to frig around with the paperwork. Also, unfortunately, every time I opened part 61 my eyes suddenly glazed over and I got a terrible thirst coupled with a dire need to be elsewhere.
